To enter major North American retail supply chains including Walmart, Amazon, and Costco,WERCS registration is mandatory for lithium batteries, cells, and battery-powered devices.However, many suppliers still face operational challenges and knowledge gaps.

This article covers the Top 10 Frequently Asked Questions about WERCS registrationto help you achieve smooth compliance.

Q1: Can I register on WERCS without a UPC barcode?

Yes.If your product is a component (cell, battery pack) supplied to downstream manufacturersand not sold directly to consumers, you may use Component Registration,which does NOT require a UPC.Once registered, your downstream customers can directly link your component in their WERCS account.

Q2: What are common UPC input errors in WERCS?

Incorrect digit length: Only 12-digit or 14-digit UPCs are accepted.
Leading zero: Do NOT include leading zeros; they cause invalid status.
Unofficial or duplicated codes: Non‑GS1, placeholder, or reused codes fail retail linkage.

Q3: What is the difference between Component Registration and Finished Goods Registration?

表格

Item	Component Registration	Finished Goods Registration
For	Batteries, cells, intermediate parts	Finished products for retail sale
UPC Required?	No	Yes (valid GS1 UPC mandatory)
Purpose	For downstream customer linkage	Retail compliance & shelf approval
Required Docs	SDS, UN38.3, product photos	SDS, UN38.3, packaging info, UPC

Q4: My finished product contains a battery. What should I note?

Follow the Component‑First Rule:

The battery supplier must complete WERCS Component Registration first.
When registering your finished product, you must link the battery’s WERCS ID.
If the battery is not registered, your finished product registration will be rejected.

Q5: How is WERCS registration fee calculated? Is it one‑time?

WERCS uses tiered subscription pricing based on total product count,not per‑product fees.Plan your registration volume to avoid extra costs from frequent tier upgrades.

Q6: How long is WERCS registration valid?

All products share the same validity period as your account subscription,not individual registration dates.

Active subscription → all products remain valid
Expired subscription → all products become invalid simultaneouslyRenew at least 30 days before expiration to avoid disruptions.

Q7: Can I use a Chinese‑only SDS?

No.WERCS requires SDS in English & French bilingual format,compliant with North American regulations (OSHA HazCom 2012, WHMIS 2015).Single‑language SDS will be rejected.

Q8: Is UN38.3 report mandatory? Which products need it?

Yes.All lithium‑containing products — lithium‑ion, lithium‑metal, and battery‑embedded devices —must submit a valid UN38.3 test report issued by an ISO 17025 accredited laboratory.

Q9: Why does the system show “Component Not Found”?

Possible causes:

Battery supplier has not completed registration.
Component registration is still pending (takes 2–3 business days to sync).
Entered name or ID does not match the registered component.

Q10: Can I edit product information after registration?

Yes, but with restrictions.

Changes to key fields (product name, UPC, packaging) may trigger re‑approval.
Some edits may require retailer re‑authorization.Double‑check information during initial registration to avoid delays.
